The LC331IC Integrated Communications Module is an integral part of the IED LANcom SCS that provides basic program distribution and intercom communication functions. The LC331IC uses a single CAT5e or better (with RJ45 connector) Ethernet connection for power, control data and digital audio signals In and Out. It receives its power from an IED LANcom SCS Power Injector, typically located in the telecommunications closet. Peripheral devices, such as call switches and loudspeakers are connected using RJ-45 or Phoenix/Euro block terminal connectors.
